研究人员对生活在小岛上的41只猴子进行了用手习惯的测试，他们向每只猴子扔了10到20次花生，并记录下哪只手把花生捡起来。在5%的置信水平下判断利手性。在20次试验后显示对左手或右手没有偏好的动物被认为是左右手。以下分布的利手被发现：左手，17（41%）;右手，8（20%）;双手，16（39%）。这些发现与其他关于日本猴子利手的研究进行了比较。惯用手的猴子数量多于惯用双手的猴子，而惯用左手的猴子数量多于惯用右手的猴子。利手的特征分布被证明是无关的部队。通过查看来自这些不同来源的数据，日本猴子中左撇子、左右手和右撇子的比例分别估计为39%、33%和28%。本研究中所使用的方法与Kawai的“捕捉行为”进行了比较，并讨论了对利手判断不一致的原因。
Forty-one monkeys living on the Koshima Island were tested for handedness by throwing a peanut 10 or 20 times toward each subject and recording which hand was used to pick it up. Handedness was judged at the 5% level of confidence. Animals showing no preference for the left or right hand after 20 trials were considered to be ambidextrous. The following distribution of handedness was found: left-handed, 17 (41%); right-handed, 8 (20%); ambidextrous, 16 (39%). These findings were compared with other studies on the handedness of Japanese monkeys. Handed monkeys outnumber the ambidextrous ones and the left-handed monkeys outnumber the right-handed ones. The characteristic distribution of handedness was shown to be irrespective of troop. By looking over the data from these different sources, the proportions of the left-handed, the ambidextrous, and the right-handed in Japanese monkeys were estimated at 39%, 33%, and 28% respectively. The method used in this study was compared withKawai's “catching behavior” and reasons for disagreement between judgments of handedness were discussed.
